Key improvements moving forward

FPL supports Puerto Rico

► 140 lineworkers, management and support staff on island since early January

► Employees are working with 10-person FPL Incident Management Team

► Restoring service to residents in Bayamon

Our crews face many challenges in the restoration effort

► Inaccessible locations are part of the daily work

Man-baskets and rear-of buckets help overcome

challenges with terrain and construction practices

Crews continually adjust work methods to safely

and quickly restore customers

► Crews reusing materials

► Driving, MOT and road conditions are a large safety

issue

We’re finding opportunities to make an impact

► Meetings between PREPA, USACE, Fluor and

vendors to coordinate work

► Crews are giving back to the community

Local children have received gifts from

lineworkers, which has been meaningful to

families
